ABSTRACT

A structural frame of an aircraft lavatory unit includes a first side wall facing a latitudinal aisle, and boarding entrances are located at both ends of the latitudinal aisle. A pump-type bottle that can discharge a disinfectant for hands and fingers is disposed at the first side wall at a height at which a passenger can push down a head portion thereof.

TECHNICAL FIELD

The present technology relates to an aircraft lavatory unit.

BACKGROUND ART

In recent years, measures for preventing infections with a novelcoronavirus have been widely taken in various countries around theworld. Most of the infections with the novel coronavirus are said to becaused by touching eyes, a nose, or a mouth with hands and fingers withviruses attached due to contact with objects.

It is preferable to take measures to prevent the infections with thenovel coronavirus also in an aircraft cabin.

The present inventor intensively studies prevention of spread ofpassenger-to-passenger infections with the novel coronavirus attached tohands and fingers due to contact with objects in an aircraft cabin, andfocuses on a handle of a door for opening and closing an entrance of anaircraft lavatory unit.

That is, on a long-distance flight for five or six hours or more, everypassenger uses the aircraft lavatory unit at least once.

In other words, on the long-distance flight, every passenger touches thehandle of the entrance door of the aircraft lavatory unit.

Then, if cabin attendants disinfect the handle of the entrance door ofthe aircraft lavatory unit every time a passenger uses the aircraftlavatory unit, there is no possibility of infecting other passengerseven with the novel coronavirus that has attached to the handle.

Unfortunately, some airlines reduce the number of cabin attendants fromthe viewpoint of cost reduction or the like, and thus cabin attendantsmay not be able to disinfect the handle of the entrance door of theaircraft lavatory unit every time a passenger uses the aircraft lavatoryunit.

In such a case, passengers who do not want to be infected with the novelcoronavirus can disinfect their hands and fingers with, for example, owntissues impregnated with a disinfectant after leaving the aircraftlavatory unit but cannot disinfect their hands and fingers if theyforget to bring tissues impregnated with a disinfectant.

SUMMARY

The present technology provides an aircraft lavatory unit that enablespassengers to disinfect their hands and fingers every time they use theaircraft lavatory unit and is advantageous in preventing infections witha novel coronavirus in a cabin.

One embodiment of the present technology is an aircraft lavatory unitdisposed in an aircraft comprising a longitudinal aisle extending in afront-rear direction of a fuselage, a latitudinal aisle extendingperpendicularly to the longitudinal aisle, and seat groups provided onboth sides of the longitudinal aisle, the aircraft lavatory unit facingat least one of the longitudinal aisle or the latitudinal aisle. Astructural frame of the aircraft lavatory unit includes a wall portionfacing the at least one of the longitudinal aisle or the latitudinalaisle, and a pump-type bottle that can discharge a disinfectant forhands and fingers is disposed at the wall portion at a height at which apassenger can push down a head portion of the pump-type bottle.

According to the present technology, when using the aircraft lavatoryunit, passengers can push down the head portion of the pump-type bottleto discharge a disinfectant to their hands and fingers and easilydisinfect them.

Therefore, even if every passenger touches the handle of the aircraftlavatory unit on a long-distance flight, the embodiment is advantageousin preventing the infections with the novel coronavirus to otherpassengers via the handle of the aircraft lavatory unit and thus isadvantageous in preventing the infections with the novel coronavirus inthe aircraft cabin.
